Medicare Advantage Network Reforms: What Physicians, Hospitals, and Healthcare Organizations Need to Know

New federal requirements strengthen network directory accuracy, protect beneficiaries from unexpected costs, and increase insurer accountability for information that affects patient access and healthcare businesses.

Medicare Advantage insurers control the network directories that beneficiaries use to identify participating physicians, hospitals, and other healthcare organizations. Inaccurate listings can misdirect patients, disrupt referrals, and trigger disputes over network participation, coverage, and reimbursement. For healthcare organizations that depend on timely and accurate payment for medical services, these problems threaten patient relationships, revenue, and business operations.

The Requiring Enhanced and Accurate Lists of (REAL) Health Providers Act, enacted as part of the Consolidated Appropriations Act 2026, establishes new standards for Medicare Advantage network directories. Proposed regulations from the Centers for Medicare & Medicaid Services (CMS) would implement verification, updating, and reporting requirements beginning in 2028, followed by public accuracy reporting in 2029. These reforms place greater responsibility on insurers for the accuracy of information that beneficiaries rely on when selecting healthcare professionals and facilities.

Why This Matters

Physicians, hospitals, and other healthcare organizations negotiate and maintain network relationships with Medicare Advantage insurers, but they do not control how insurers present their participation to beneficiaries. An outdated practice location, incorrect network designation, or inaccurate statement about accepting new patients can interfere with access to care and create financial disputes. Stronger insurer accountability may reduce these problems, while new contractual and documentation requirements create additional obligations for participating healthcare organizations.

Stronger Verification and Updating Requirements

Beginning in 2028, Medicare Advantage organizations would have to verify directory information at least every 90 days for most participating physicians and other healthcare professionals. Specified hospitals and facilities would follow a 12-month verification schedule. Verification would address network participation, practice locations, acceptance of new patients, and other information beneficiaries need to obtain covered services.

Insurers would also have to remove a physician or other healthcare organization from a directory within five business days after determining that it no longer participates in the network. If an insurer cannot verify information during the applicable verification cycle, it must identify the listing as potentially inaccurate. These requirements place greater responsibility on insurers to maintain reliable directories and communicate changes in network participation.

Patient Protections and Reimbursement Implications

Inaccurate network information can expose beneficiaries to unexpected medical expenses. Under the proposed framework, a beneficiary who schedules an appointment with an out-of-network physician or healthcare organization listed as participating in the Medicare Advantage plan’s directory on the appointment date would qualify for cost-sharing protection if the services otherwise qualify for coverage. The insurer would have to limit the beneficiary’s financial responsibility to the lesser of the applicable in-network or out-of-network cost-sharing amount.

The protection applies to the beneficiary’s financial responsibility, not necessarily the healthcare organization’s reimbursement. It does not automatically require an insurer to pay an out-of-network physician or healthcare organization at an in-network contractual rate. Patient cost-sharing protections and the organization’s right to payment remain separate legal and contractual questions, leaving room for reimbursement disputes even when the beneficiary receives financial protection.

Participating healthcare organizations would also face new contractual documentation obligations. Medicare Advantage insurers would have to include provisions requiring them to produce records establishing the earliest date a beneficiary scheduled an appointment, regardless of subsequent rescheduling. Separately, insurers would have to maintain daily archives of their network directories for at least 10 years. These requirements increase the importance of accurate scheduling records and historical network information when disputes arise over a beneficiary’s eligibility for cost-sharing protection.

Greater Transparency and Insurer Accountability

Annual directory accuracy assessments would require Medicare Advantage insurers to evaluate and report the reliability of their network information. Beginning in 2029, CMS would publicly report directory accuracy scores, and insurers would have to prominently display their scores. Public reporting would give beneficiaries and healthcare organizations greater visibility into the reliability of insurer networks.

The proposed regulations would also require disclosure of common ownership or control between Medicare Advantage organizations and certain participating healthcare businesses. These disclosures would provide greater transparency into relationships involving insurers, affiliated medical groups, and facilities, particularly where integrated business arrangements influence network structure, referrals, and payment relationships.

Impact on Healthcare Organizations and Physicians

Physicians, medical groups, hospitals, and other healthcare organizations stand to benefit from more reliable network information and stronger insurer accountability. Accurate directories can improve patient access, reduce confusion over network participation, and limit disputes arising from incorrect listings. At the same time, new documentation requirements and existing reimbursement arrangements create legal and operational considerations that extend beyond directory maintenance.

Healthcare organizations must distinguish an insurer’s obligation to protect beneficiaries from its separate obligations to pay for medical services. Network contracts, scheduling records, reimbursement relationships, and information communicated to patients can all influence how coverage and payment disputes develop. For owners, executives, and investors, these issues affect more than administrative compliance. They influence patient access, revenue stability, and the financial performance of healthcare businesses.

Key Takeaway

The Medicare Advantage reforms place greater responsibility on insurers for the accuracy and reliability of the networks they present to beneficiaries. Stronger directory standards and greater transparency can improve patient access while bringing renewed attention to network participation, contractual obligations, and reimbursement relationships. Physicians, hospitals, and other healthcare organizations that understand these changes will be better positioned to protect their patient relationships and business interests as implementation approaches.
